I have been eating approx 1/2 of what I used to eat, however my stomach is even bigger?

I am 59.. weight 280. For 2 weeks I have been eating approx 1/2 of what I used to eat, however my stomach is even more extended than normal and appears to grow daily. My legs and feet are extremely swollen. I recently changed jobs so I am currently without insurance or I would go to doctor. Also I have a red rash from feet to chins. Any thoughts?
